Ectograph: Ghost Spirit Box

An offline spirit box that reads the room through the sensors in your phone, from the EMF meter to light and pressure. Ask out loud and listen for the answer.

Take it into the basement or a building with no signal. Ectograph is a ghost box and EMF ghost detector for paranormal investigation. Tap Start session and ask your first question. Use this spirit box during ghost hunting or a quiet ITC session at home.

ASK THE SPIRIT BOX

Ask and wait. When the readings change, a voice answers from the static: a single word or a short phrase. It appears over the vortex and is written to the live transcript. You never know who will answer.

Keep the spirit box quiet and only read the words, or let every response speak. A response chime and a haptic pulse can mark each one.

EMF METER AND A FULL SENSOR ARRAY

• The spirit box listens to the whole array: magnetic field, motion, light, pressure and proximity. A change in any of them can bring a word at any moment.
• The EMF meter shows magnetic-field deviation from ambient, with an LED ladder and a microtesla readout. Follow EMF changes while you ask the spirit box your next question.
• Open Sensors for live EMF and motion readings, including accelerometer, gyroscope and gravity, plus light, pressure and proximity. Temperature and humidity appear where your phone supports them.
• Missing sensors are marked unavailable. The ghost box does not invent a number.

RECORD YOUR SPIRIT BOX SESSION

Recording is optional and off by default. Turn it on to capture video of the screen with the app's sound and your voice. Add your face in a small front-camera bubble, or turn the face view off in Settings.

• Play your spirit box session back with a scrubber marked at every word.
• Change playback speed from 0.25x to 2x, skip five seconds, or jump to the previous or next word.
• Save the video to your phone's gallery or a folder you choose. You can also share the whole recording.

KEEP YOUR SPIRIT BOX SESSION HISTORY

Every spirit box session is saved with a timestamped transcript of every response. Bookmark a session from the attic, filter for sessions with responses or bookmarks, or sort oldest first. Share a session summary or clear the log any time.

An optional location tag, off by default, puts the session on a map on its card. Locations stay on your device. Map tiles need internet the first time they load for a place; everything else works offline.

PACK YOUR GHOST BOX

Use the spirit box alongside an EVP recorder and an EMF meter in your ghost hunting kit. In an empty hallway or during a seance, keep the EMF readings in view as you listen. Bring the spirit box on every paranormal investigation and ghost hunting trip, next to your ghost detector and camera.
